Warming commitments

Posted on January 8, 2021 by ...and Then There's Physics

There’s been quite a lot of recent discussion about warming commitments. It started with an article by Bob Berwyn called Net Zero Emissions Would Stabilize Climate Quickly Says UK Scientist, followed soon after by one saying [w]arming already baked in … Continue reading →

Have CO2 emissions peaked?

Posted on January 2, 2021 by ...and Then There's Physics

I noticed, as has Stoat, that Ken Caldeira and Ted Nordhaus have a bet about whether or not we’ve reached peak CO2 emissions. Specifically, the bet is Between 2021 and the end of 2030, annual fossil fuel emissions (excluding carbonation) … Continue reading →

The impact of 4C of global warming

Posted on May 20, 2019 by ...and Then There's Physics

On a number of occasions I’ve highlighted Kevin Anderson saying At 4oC most of the scientists I talk to about this, and the social scientists as well, would say it’s incompatible with organised global community. I don’t know if this … Continue reading →

Research should inform, not influence

Posted on August 5, 2018 by ...and Then There's Physics

Thomas Basbøll, who I sometimes have discussions with on Twitter, has a guest post on the LSE impact blog claiming that we need our scientists to build models that frame our policies, not to tell stories that shape them. If … Continue reading →

What if global warming ends up being greater than we thought?

Posted on December 17, 2017 by ...and Then There's Physics

I recently wrote a post about the Brown & Caldeira paper which suggests that climate sensitivity may be on the high side of the range. Rather predictably, Nic Lewis has a guest post on Climate Etc in which he looks … Continue reading →

Greater future global warming?

Posted on December 8, 2017 by ...and Then There's Physics

Before I go out I wanted to briefly mention a recent paper by Patrick Brown and Ken Caldeira called [g]reater future global warming inferred from Earth’s recent energy budget. Patrick Brown already has a nice blog post about this with … Continue reading →

Hawking is wrong

Posted on July 7, 2017 by ...and Then There's Physics

I guess the big alarmist news at the moment is that Stephen Hawking has been quoted as saying: Trump’s action could push the Earth over the brink, to become like Venus, with a temperature of two hundred and fifty degrees, … Continue reading →

We might not be certain, but…..

Posted on April 29, 2017 by ...and Then There's Physics

Bret Stephens, the newly appointed Op-Ed writer for the New York Times, has released his first column to much criticism. It’s a rather strawman-laden column in which he essentially argues that it’s okay to doubt climate science, and/or climate policy, … Continue reading →

Maximum warming

Posted on January 4, 2015 by ...and Then There's Physics

There’s an interesting new paper by Katharine Ricke and Ken Caldeira called Maximum warming occurs about one decade after a carbon dioxide emission. The basic result of the paper is that the median time between the emission of some CO2 … Continue reading →
